A Reciprocity Method for Multiple-Source Simulations

Reciprocity is applied to the situation where simulations are needed for a number of source locations, but relatively few receiver positions. By invoking source-receiver reciprocity, the number of simulations can be generally reduced to three times the number of receiver positions. The procedure is demonstrated for a heterogeneous medium with both single force and double couple sources. The numerical tests using a finite-difference implementation show that the reciprocal simulations can be performed with the same level of accuracy as the forward calculations.
